Listen Up: Perceptions Of Audiobooks By Teachers, Librarians, And Parents, Megan Bright

Murray State Theses and Dissertations

Reading is a critical component of education. From learning to read, to eventually reading to learn, students and teachers rely upon texts to help make sense of the world around them. Methods and tools vary, but teachers, librarians, and parents can all agree that reading is a fundamental skill their students need. However, students are sometimes told to limit their use of audiobooks in favor of reading with their eyes. These limitations may prevent students from finding the books they love and also limit students’ opportunities to use books to learn about the world around them. This study sought to …

Examining Stigma In Rural Mental Health Care Settings: A Mixed Methods Approach, Lainie Krumenacker

Murray State Theses and Dissertations

More than half of Americans will be diagnosed with a mental illness in their lifetime (CDC, 2021), yet stigma towards mental health affects both patients and providers. Although programs exist to address stigma, improve cultural competency among providers, and educate families on the importance of support, facilities are often limited on programs they provide due to allocation of resources and funds. Without a shift in treatment and programing, stigma will continue to impact patient care and outcome.

This study explored stigma among mental health providers in rural communities, while exploring potential differences in treatment among patients due to race. Mental …

A Comparison Of Student Achievement On Agriculture Mechanics End Of Pathway Assessments Among Agriculture Programs In Georgia, William Burt

Murray State Theses and Dissertations

Agriculture education programs in Georgia are held to the same standards and evaluations regardless of their location, resource availability, and student clientele. For schools with agriculture mechanics programs specifically, students are expected to obtain proficient skills in welding, electrical wiring, woodworking, small engines, concrete, and machinery. Students' are expected to obtain skill sets in these various content areas, yet the equipment and resources available to the educator differs among schools. The experience that a student encounters also differs among schools. For instance, some schools have multiple agriculture pathways for a student to enroll in, while other schools have minimal. The …

Take My Perspective, Please: Perspective Taking’S Impact On Insecure Attachment And Phubbing, Connor Brown

Murray State Theses and Dissertations

Phubbing is defined as the act of ignoring another individual (e.g., significant others, friends) by devoting attention to one's phone (Chotpitayasunondh & Douglas, 2018). Previous literature indicates that insecurely attached (anxious and avoidant) individuals are more likely to phub than others (Sun & Miller, 2023a). This study examined correlations between attachment styles and phubbing, finding that avoidant attachment was not significantly correlated with phubbing, while anxious attachment was. As well as examining the correlation between phubbing and perspective taking, results indicate that there was not a significant correlation. The primary interest of this study sought to investigate perspective taking as …

A Critical Evaluation Of "Leakage" At The Cochlear Blood-Stria-Barrier And Its Functional Significance, Kevin K Ohlemiller, Noël Dwyer, Veronica Henson, Kaela Fasman, Keiko Hirose

2020-Current year OA Pubs

The blood-labyrinth-barrier (BLB) is a semipermeable boundary between the vasculature and three separate fluid spaces of the inner ear, the perilymph, the endolymph and the intrastrial space. An important component of the BLB is the blood-stria-barrier, which shepherds the passage of ions and metabolites from strial capillaries into the intrastrial space. Some investigators have reported increased "leakage" from these capillaries following certain experimental interventions, or in the presence of inflammation or genetic variants. This leakage is generally thought to be harmful to cochlear function, principally by lowering the endocochlear potential (EP). Here, we examine evidence for this dogma. We find …

METHODS: A systematic literature search was performed from October 2020 to May 2022 in PubMed, CINAHL, Scopus, Global Health, and the Web of Science. Studies included in the review were conducted among young people aged 10-24 living in Africa, written …

Modular Horizontal Network Within Mouse Primary Visual Cortex, Andreas Burkhalter, Weiqing Ji, Andrew M Meier, Rinaldo D D'Souza

2020-Current year OA Pubs

Interactions between feedback connections from higher cortical areas and local horizontal connections within primary visual cortex (V1) were shown to play a role in contextual processing in different behavioral states. Layer 1 (L1) is an important part of the underlying network. This cell-sparse layer is a target of feedback and local inputs, and nexus for contacts onto apical dendrites of projection neurons in the layers below. Importantly, L1 is a site for coupling inputs from the outside world with internal information. To determine whether all of these circuit elements overlap in L1, we labeled the horizontal network within mouse V1 …

Negligence In Biomedical Research: An Anti-Racist Approach For Substance Use Researchers, Jonathan Lehman, Danniella Balangoy, Angie P Mejia, Carlos Cardenas-Iniguez, Scott Marek, Anita C Randolph

2020-Current year OA Pubs

Racism is embedded in the fabric of society at structural, disciplinary, hegemonic, and interpersonal levels, working as a mechanism that drives health disparities. In particular, stigmatized views of substance use get entangled with racialization, serving as a tool to uphold oppressive systems. While national health institutions have made commitments to dismantle these systems in the United States, anti-racism has not been integrated into biomedical research practice. The ways in which substance use researchers use and interpret race data-without engaging in structural racism as a mechanism of health inequity-can only be described as inadequate. Drawing upon concepts from the Public Health …

2020-Current year OA Pubs

Traditional patient- and provider-level hypertension interventions have proven insufficient to halt hypertension as the leading cause of morbidity and mortality globally. Systems-level interventions are required to address factors challenging hypertension control across a social ecological framework, an under-studied topic particularly salient in low- and middle-income countries (LMICs) such as Peru. To inform such interventions, we sought to identify key health systems barriers to hypertension care in Puno, Peru. A participatory stakeholder workshop (October 2021) and 21 in-depth interviews (October 2021-March 2022) were conducted with 55 healthcare professionals (i.e., doctors, nurses, midwives, dentists, nutritionists), followed by a deductive qualitative analysis of …

2020-Current year OA Pubs

BACKGROUND: Opinion leadership, educational outreach visiting, and innovation championing are commonly used strategies to address barriers to implementing innovations and evidence-based practices in healthcare settings. Despite voluminous research, ambiguities persist in how these strategies work and under what conditions they work well, work poorly, or work at all. The current paper develops middle-range theories to address this gap.

METHODS: Conceptual articles, systematic reviews, and empirical studies informed the development of causal pathway diagrams (CPDs). CPDs are visualization tools for depicting and theorizing about the causal process through which strategies operate, including the mechanisms they activate, the barriers they address, and …

Protocol For A Pilot Clinical Trial Of The Senolytic Drug Combination Dasatinib Plus Quercetin To Mitigate Age-Related Health And Cognitive Decline In Mental Disorders [Version 2; Peer Review: 1 Approved, 2 Approved With Reservations], Abigail Schweiger, Breno Diniz, Ginger Nicol, Julie Schweiger, Andes E Dasklakis-Perez, Eric J Lenze

2020-Current year OA Pubs

BACKGROUND: Major depressive disorder (MDD) and schizophrenia are linked to accelerated aging leading to reduced lifespan, health span and cognitive decline. Cellular senescence, in which cells lose proliferative capacity and develop a senescence-associated secretory phenotype (SASP), plays a role in this process. Emerging research suggests that the senolytic regimen of dasatinib+quercetin (D+Q) reduces senescent cells, potentially mitigating age-related health and cognitive decline. This pilot study aims to assess the feasibility and safety of D+Q in older adults with schizophrenia, schizoaffective disorder, and treatment-resistant depression (TRD).

METHODS: This single-center study will recruit 30 participants total aged 50 years or older with …

Arid1a Loss Is Associated With Increased Nrf2 Signaling In Human Head And Neck Squamous Cell Carcinomas, Vinh Nguyen, Travis P. Schrank, Michael B. Major, Bernard E. Weissman

2020-Current year OA Pubs

Prior to the next generation sequencing and characterization of the tumor genome landscape, mutations in the SWI/SNF chromatin remodeling complex and the KEAP1-NRF2 signaling pathway were underappreciated. While these two classes of mutations appeared to independently contribute to tumor development, recent reports have demonstrated a mechanistic link between these two regulatory mechanisms in specific cancer types and cell models. In this work, we expand upon these data by exploring the relationship between mutations in BAF and PBAF subunits of the SWI/SNF complex and activation of NRF2 signal transduction across many cancer types. ARID1A/B mutations were strongly associated with NRF2 transcriptional …
